General

Are these cartridges compatible with my device (M8S, A9, A20, A6S, A11, M8, H6)?

Our products are compatible replacements designed for the listed model categories on each product page. Always select the exact model-specific option; lock shapes can differ by series.

Are cartridges interchangeable across different models (e.g., M8 vs. A6S)?

Generally no. Treat cartridges as model-specific unless the product page explicitly states cross-compatibility.

Can I reuse a cartridge?

No. All cartridges are single-use, individually sterile-packed. Reuse is unsafe and not recommended.

What do the pin counts (11/12/16/24/36/42) actually mean?

They indicate needle density per tip. Higher counts cover more area per pass; lower counts are often chosen for more targeted work. Choice depends on your project and professional guidance.

Returns & exchanges—what if I ordered the wrong model?

Please review our Returns Policy. Unopened, unused items in original packaging are usually eligible within the stated window.

Do you offer wholesale or private label (OEM)?

Yes. We support wholesale packs and OEM/private label projects. Contact sales with your volumes and packaging needs.

What’s the difference between Nano and microneedling pin cartridges?

Nano tips are designed for gentle, surface-level applications and serum/makeup infusion; pin tips (11–42) are used in microneedling workflows. See product pages for details and consult a professional.

How do I choose the right cartridge for my model?

Use the model category (e.g., M8 Cartridges) and then pick a pin count or Nano variant. If unsure, contact support with your device name and photos of the handpiece and original tip.

Do you provide a needle depth chart?

We offer an educational needle depth overview for common areas. It is not medical advice—follow your device instructions and professional guidance.

What pack sizes are available?

Most items offer 10 / 20 / 50 / 100-pack options. Larger packs are popular for clinics and routine use.

Can I mix cartridges across different users?

No. Cartridges are single-use and must not be shared or reused across users.

Are you affiliated with Dr. Pen?

No. We supply compatible replacement cartridges. We are not affiliated with or endorsed by the brand owner.

Which cartridges are most popular for M8/M8S?

Frequently ordered: 12-pin, 16-pin, 36-pin, 42-pin, and Nano. Availability may vary; check the M8 or M8S category pages.

Do you offer A-series options like A6S or A11?

Yes—see A6S Cartridges and A11 Cartridges categories for model-specific tips and pack sizes.

What should I do if I’m unsure whether my device is A9 or A20?

Compare the model label on your handpiece and the original tip shape with our product photos. If still unsure, contact support— we can help identify compatible options.

How should I store cartridges?

Keep sealed pouches in a cool, dry place, away from direct sunlight or moisture. Discard any pouch that’s torn, punctured, or opened.

Shipping & delivery—do you ship internationally?

Yes, we offer tracked international shipping. Transit times and duties/taxes depend on your country and chosen service.
